Thanks Rcolistete. Speaking of the several mathematical tools you have been developping, do you plan on porting R to Sailfish? I remember being able to run my R scripts or do calculations in R using Easy Debian in Maemo 5, and it was very convenient. I don't remember if it was working on your Easy Debian version for Harmattan. Anyway, I think there is nothing on Sailfish yet, and R would be a very good integrated mathematical software where almost any calculation would be possible.
